Error propagation is the main problem in transmitting a real-time interactive video over the Internet. A lot of work and research has been done to solve this problem. Periodic FEC[4], proposed by Choi et al., is a scheme that prevents error propagation with small redundant information. However, this scheme does not have an effective redundancy control mechanism to adapt to network conditions. In this paper, an ACK-based redundancy control mechanism is proposed to reduce the amount of redundancy based on current network conditions. Also, we propose a TCP-friendly redundancy control algorithm of Periodic FEC to have a similar bandwidth with the TCP control mechanism. Through simulations, we confirm that the proposed algorithm provides a good PSNR when the network conditions are good and shares a similar bandwidth with TCP.
